Spread and popularity of ad blockers is a growing threat for publishers, study finds

A major new study by Reuters (summarized by a story in the Columbia Journalism Review), on the state of digital news says that the growing use of ad blockers threatens not only legacy publications (in other words, print) but also the disruptors (in other words, things such as Buzzfeed and Huffington Post). Just 11% of US consumers are paying for online news and this hasn't increased since 2013.
